I am currently working with Unreal and the 'Editor Scriptable Tool' plugin. I am trying to create a scriptable tool that can manage houdini sessions, UI parameters, HDA inputs and so on.
The HDA that I am working with requires a landscape input. I feed this input through a Property Set and it worked fine until today.
When I click on my HDA to look at the input that it actually using, it says: "(deprecated) Landscape Input".
The landscape is not the issue as when I fill the HDA input manually it works fine.

Anybody any clue?
